What this skill does
Refine rule Always-loaded files pay their cost every session; prune hardest here. Apply agent-copy; Read it first if not already loaded. Checks specific to rule and memory files: Right file for the audience. Harness-agnostic guidance in AGENTS.md; harness-specific mechanics in that harness's file (CLAUDE.md, .cursor/rules/.mdc). Cursor rules scope by glob; prefer a scoped rule over an always-apply one. When a skill covers the topic, the memory file keeps one pointer line. Restated bullets drift from the skill. Delete what context will supply. "When working on X, do Y" is suspect: Y is often self-evident inside X, visible in the files being edited or surfaced by typecheck, lint, or tests. Can be found ≠ will be encountered; facts in obscure corners stay written down. Under 50 lines per section. Longer is sediment. Verify every fact. Paths, model names, and tool flags rot silently in files nothing typechecks.
How to use it
Reference it in AdaL, Claude Code, Cursor or any coding agent — nothing to install:
